The amount of oxygen required for combustion is more than the air alone can provide. Especially when the air is getting thinner with altitude and eventually the rocket leaves the atmosphere.
Ambulances carry oxygen cylinders because it is often used to revive people, e.g. For people rescued from drowning or people rescued from smoke filled rooms.Hospitals also use it for patients with breathing difficulties e.g. asthma.

Yes it is a fossil fuel.
The atmosphere surrounding Earth provides oxygen for living organisms to breathe and carry out cellular respiration, which is the process that releases energy from food. This oxygen is essential for sustaining life on Earth.
Major arteries like the aorta transfer oxygenated blood from the heart to the body tissues.Coronary arteries are those branches from the major aorta that feed the heart with oxygenated blood.Arteries are the vessels which carry oxygen-rich blood away from the heart, except for the pulmonary artery, which is the only artery (besides umbilical arteries inside of a fetus) that carries deoxygenated blood. The pulmonary artery carries blood away from the heart into the lungs.The thing that carries oxygen in your blood is the protein hemoglobin.Arteries always carry blood away from the heart. Veins always carry blood back to the heart. Not all arteries carry high O2 blood. Not all veins carry low O2 blood. They are named for where they go not what they carry.
A rocket carries its own oxygen because it needs oxygen to enable combustion of fuel for propulsion in the vacuum of space where there is no atmospheric oxygen. This allows the rocket to generate thrust and propel itself forward.
Rockets carry oxygen into space as part of their propellant mixture to enable combustion with the rocket's fuel. This reaction generates the necessary thrust to propel the rocket forward. Oxygen is crucial for combustion to occur in the rocket engine, allowing the propulsion system to function effectively in the vacuum of space.
Rocket fuel contains oxygen, which is not found in space. A rocket in space could theoretically work in space if it were to carry its own oxygen, but other fuels such as hydrogen are more efficient.
Rocket motors carry their own oxygen supply (oxygen is important for combustion), whereas automobile engines do not - they draw their oxygen from the air taken in from outside the vehicle.

Rockets carry their own oxidizer to burn their fuel in space, as there is no oxygen available in space for combustion. The fuel and oxidizer react together in the rocket engine to produce thrust, allowing the rocket to move forward. This allows rockets to function in the vacuum of space where there is no atmospheric oxygen.
a rocket may carry space equipment
A rocket has it's own supply of oxygen.
The oxygen in a rocket can come from either cryogenic liquid oxygen stored onboard the rocket, or from onboard solid rocket fuel that contains its own oxidizer, such as ammonium perchlorate. In both cases, the oxygen is used during the combustion process to react with the fuel and generate thrust.
In space there is no oxygen. Space is a vacuum. All things like a rocket going to space, require a fuel to burn, oxygen and a heater. Since there is no oxygen is space they need to provide it for them. Meaning the reaction can take place correctly.
The rocket carries its own supply of oxygen with which to burn the fuel.
